A data network comprises a plurality of spatially distributed stations whose access to the network is controlled by a token. In a process for real-time transmission of data packets through the data network, the following steps are carried out in each of the stations: assigning a priority step to each data packet to be transmitted depending on the dwell time of the data packet in the station, and summing up the data amounts of the respective data packets having the same priority step; reserving in the token, send capacity required for transmitting data packets, said reservation being effected in dependence upon the send capacity available, the priority and the data amount of the data packets to be transmitted from this station, and information which is contained in the token and which concerns the priority and the data amount of data packets to be transmitted from other stations; and transmitting the data packets corresponding to the reserved send capacity when the token is next received.
